摘要：
An improved coal deashing process wherein a feed mixture comprising soluble coal products, insoluble coal products, and deashing solvent at a first temperature level is separated in a first separation zone into a first light fraction and a first heavy fraction comprising the insoluble coal products and some of the deashing solvent through admixing predetermined quantities of an additive with the feed mixture prior to separation to provide an improved yield of recoverable soluble coal products. Alternatively, the additive is admixed with the first light fraction prior to subsequent separations to provide an improved yield of recoverable soluble coal products.
